Alterations To Existing Buildings

Making Alterations To An Existing Building

Section 112 of the Building Act requires Council to consider the effect and level of improvements proposed for a building consent application for alterations to an existing building.

Other than under specific clauses, Council cannot grant a building consent for alterations unless it is satisfied that after the alteration, the building will comply with the following:

​As near as is reasonably practicable, with the requirements for the means of escape from fire and access and facilities for persons with disabilities; and

The building will, if it complied with the other provisions of the Building Code immediately before the building work began, continue to comply with those provisions; or if it did not comply with the other provisions of the Building Code immediately before the building work began, continue to comply at least to the same extent as it did then comply.

For alterations to an existing residential building, the proposal should include the provision of smoke detection, if it is not already installed in the building.

Building consent applications for alterations to commercial buildings require a more detailed assessment and the application will need to include an assessment against the applicable current code requirements. The assessment will need to justify the proposed solution if it is proposing an as near as is reasonably practicable solution.

If you are thinking of carrying out alterations to a commercial building, Council recommends you seek professional advice and organise a pre-lodgement meeting with a member of our building control team prior to submitting an application.

What Is A Change Of Use Of An Existing Building?

Where an owner is proposing to change the use of an existing building (or part of a building) there are some circumstances, where an owner must give notice in writing to Council of their intention.

A change of use occurs when a building's (or part of a building's) use, as defined in the regulations, changes and the new use has more onerous or additional Building Code requirements than the old use. The additional or more onerous requirements will usually mean that the fire hazard or the risk to life has increased in the build​​​ing's new use.

Council can be not​ified of a change of use to a building or part of a building either through the following:

A building consent application, where the work triggers the requirement to obtain a building consent; or

Written notification, when a building consent is not required, the notification will need to include documentation outlining compliance with Section 115 of the Building Act and the appropriate clauses of the Building Code.

If your proposed project includes the change of use of a building or part of a building, Council recommends you seek professional advice and organise a pre-application meeting with a member of our building control team prior to submitting an application or notification.

Extending The Life Of A Building

Some buildings have a specified intended lifespan, either due to Code Compliance inadequacies or because they were constructed to be temporary buildings. When a building consent is issued on a building like this, it is subject to the condition that it be altered, demolished or removed before the end of its life.

However, Council can approve an ‘extension of life’ if we are satisfied the building can continue to perform for a longer period.

If you would like to extend the life of a building you will need to provide us with written notice.

We recommend you seek professional advice and organise a pre-lodgement meeting with a member of our building control team​ prior to submitting a notification. ​
